Disclosed is a mold hanger for supporting a bottle mold in a blow molding station, the mold hanger comprising a piston and piston sleeve fully contained within the mold hanger configured to push a moveable insert into the mold. Also disclosed is a method of retrofitting an original rotatable blow molding module having multiple existing blow molding stations, each existing mold hanger defining an existing outer envelope. The disclosed method may include providing an improved mold hanger substantially contained within the respective existing outer envelope and including low-profile drive mechanisms configured opposably to drive moveable inserts into the mold. Further disclosed is a method of manufacturing a blow molded bottle with a deep pinch grip, the method including providing within a mold hanger a drive mechanism to drive a moveable insert into the mold. A bottle made by such methods is also disclosed.
